Even as US partisan polarization shapes climate and energy beliefs and attitudes, substantial heterogeneity in climate opinions still exists among both Republicans and Democrats. To date, our understanding of this partisan variability has been limited to analysis of national or less commonly, state-level opinion poll subsamples. The Partisan Climate Opinion Maps provide new data about how Republican and Democratic climate and energy opinions vary across all 50 states and all 435 congressional districts. They reveal new spatial patterns with policy-relevant implications for the trajectory of US climate change policy reforms. These maps have now been updated through to 2018, and give new information about the state of partisan climate and energy beliefs in the current political context.
The public opinion estimates were generated using a statistical model that combines nationally representative survey data gathered by the Yale Program on Climate Change Communication and the George Mason Center for Climate Change Communication between 2008 and 2016 with voter registration, U.S. census, and geographic data. Party registration data is available for 32 states, and is imputed in the remaining states (i.e., in Alabama, Georgia, Illinois, Indiana, Michigan, Minnesota, Mississippi, Missouri, Montana, North Dakota, South Carolina, Tennessee, Texas, Vermont, Virginia, Washington, and Wisconsin).
